New York, Aug 3 : Social networking giant Facebook has bought a digital publishing company Push Pop Press that develops technology to help make interactive books optimised for iPad and other Apple devices.

"We're thrilled to confirm that we've acquired Push Pop Press, a startup whose groundbreaking software changes the way people publish and consume digital content," Xinhua quoted Facebook as saying in a statement.

Push Pop Press was co-founded by Mike Matas and Kimon Tsinteris - both former Apple employees.

It had also teamed up with former US vice president Al Gore to create a digital version of his book "Our Choice".
